The author performed a large-scale experimental operation of a blast furnace with self-fluxing sinter burden at No.2 Kukioka Blast Furnace during the period from June 1958 to March 1959. Investigation of variable problems such as effectiveness of lime-sinter, optimum blast furnace operation measures for lime-sinter and other various problems for use of lime-sinter, were performed by this experimental blast furnace operation. So remarkable results were obtained as shown in the followings by 100% self-fluxing sinter burden : (1) The author performed productivity test during the period of December, 1958 and February, 1959 respectively. Pig iron production of more than 1, 200 ton per day was achieved during both periods. This production record corresponds to productivity factor of more than 1.4 ton per day per m^3. (2) Remarkable coke-ratio record of 518kg per ton pig iron was also achieved in November 1958. The reasons for these excellent results were investigated.
